运行异常，gdb也怪异，为什么？

新丁

我的一个程序，曾在多台机器上运行，而且是长期运行，都很正常（操作系统都是redhat9，内核2.4.20，有单cpu的，也有双cpu的），唯独有一个双cpu的机器，一运行就core，各位高手能否帮忙分析一下原因。

还有更让我纳闷的，我用gdb查看core文件显示如下：

#0 &0x40bac0fc in memcpy () from /lib/i686/libc.so.6
#1 &0x0805238d in basic_string<char, string_char_traits<char>;, __default_alloc_template<true, 0>; >;::Rep::clone (

#14 0x40b458d7 in __libc_start_main () from /lib/i686/libc.so.6

请注意红色的“#2”行，我的getNextValue()函数明明是在我自己写的文件中，gdb为什么会定位到“/usr/include/g++-3/std/bastring.h:183”？
我被困在这儿没法继续找问题了，周一前必须解决。高手帮忙呀！
